What is the WAN in Internet?
WAN stands for Wide Area Network and is a telecommunication network or computer network that extends over a large geographical distance/place. Wide are networks are often established with leased telecommunication circuits. HMI displays and PLC controllers can be used over a Wide Area Network (WAN) environment, allowing for remote monitoring, control, and data acquisition of industrial processes across geographically dispersed locations. This is typically achieved using technologies like VPNs or specialized industrial IoT platforms to ensure secure and reliable communication between the local site devices and remote operators.
